i have a short ram intake...(just bought a AEM CAI now that i have some money) and i was looking at the inside of the short ram, and its covered with motor oil. I believe this is from the tube that connects it to the valve cover. Is it sucking the oil out of the engine? is there something i can do to fix this, id rather not cake the inside of my AEM one with oil!

 

It's supposed to be a breather i.e. air goes into the valve cover or comes out, but oil comes out too...it's just the result of the design

 

that is why i run a crankcase breather, and close off the hole in the intake

 

You can put a breather on both the valve cover (one made for use with oil) and one on the intake pipe. I have that done on mine, but there is an ongoing debate about whether it is beneficial or not. I put breathers on mine for this reason: When you're racing and you go to shift, and are not power shifting, the throttle plate slams shut leaving the high velocity air to find some place to go. The only place is the idle bypass or the cold start bypass or that line connected to the valve cover. If it goes in the valve cover it pushes on the back side of the cam seal causing them to fail prematurely. This happend to me and I was not very happy to have oil gushing out of them. Mike

 

I was shocked the first time I saw that too. heres my thread on the subject, people weren't as sympathetic to me as they are being to you.

i dont put a breather on the intake cause i feel it defeats the cold air purpose of the it.

 

There is a reason for the PCV system... by cutting off the positive pressure of the air coming through the intake tube you're defeating the purpose of the system.

 

yeah, i used to have a breather on the valve cover, but it leaked oil out of it too...! all over my usually clean engine. Then i read up on the reason for this thing and i hooked it back up. I even tried to defeat it by making a copper tubing loop and hooking it up inbetween the intake and the valve cover. but still no avai.

so am i hearing that everyone out there just deals with this and lets there stuff be covered in oil? no one has a solution for this

yeah sorry for not searching well enough on this, didnt think this would be an ordinary event, never heard of it from any of my friends!

mine gets a little oil on the filter, but doesnt leak. try replacing you pcv also.

 

I have the same problem, but my car was actually burning oil (1 quart every 700 miles) and Honda saw that and tried blaming the intake.......like i tiny *** speck of oil was the reason for such massive consumption.......F*cking dicks...anyway it was also in the stock tubing because i switched everything back to stock to prove to them that wasn't it (and got a new engine if anyone cared) so i guess it just happens......

 

Would this be a good enough reason to get an oil catch tank??

 

so whats the deal here? some people say get it some say dont! I was thinking about getting one for the crank case breather..but what should i do for the other one on the cai? plug it or get one for that too?

 

if u run the breather then go to like a autostore and buy some vaccum caps and jes cap it off so no dirt would get in there . i was askn my self the question to my self should I or should i Not put a breather on. but then i went ahead and hooked up a breather and a greddy oil catch can and been running it for couple months and its running clean and the catch can seems to be werkn pretty good. and when i check my throttle body its clean and not black and oil. i have also read that geting oil in your intake manifold also lowers your octane ive read it somewhere in the TYPE R forum oh btw i have a h22 for you to know not accord motor.

 

...so let me get this striaght, you hook the oil catch can to the valve cover?!?
BTW: and you can always put that your accord has an H22 in your sig so people know and so you dont have to keep saying it, just a thought...

 

yeah i seen an oil catch can..altho i would have a hard time finding a place to mount that biatch...i dont think im getting oil in my intake..ill have to check

 

yeah kind of what i was thinking.... ughmmm maybe i should put up another post asking for pictures of where ppl have put their catch cans.. i searched for it and didnt find anything in the prelude forum

if im just a crappy searcher someone feel free to throw a link in here to some good posts

 

i dont see how the "high velocity" air would have to find a place to go.. since the car is running N/A which is a vacumme, Unless it is FI.

 

Can anyone be nice enough to post up pics of their oil catch cans installed?
Thanks!

 

my guess is from the "bounce" of the throttle body being closed suddenly is going to make a pulse of air backwards against what was the still incomming air from the vaccuum from when it was open. on a quick shift the throttle body will open, and there will be a pocket of lower pressure air right outside of it and not a more dense packet that would normally be found when sitting still (my guess is what I just explained it BS but it does sound good! )

 

What are you guys talking about? The area where the intake nipple goes is to the VALVE cover which is constantly under pressure. You want to attempt to get the gasses flowing in the correct direction (toward the PCV) and the only way to do this is by the pressure, albit small, from the intake air stream. BTW the oil catch can is NOT for the intake but for the PCV system which puts the oil into the intake manifold. It's the line from the right side of the valve cover to approximately just above the runner for cylinder 2.

 

Check your PCV. It seems it's malfunctioning if the oil is getting into your intake. The intake is supposed to force air into the valve cover and then through the engine and then through the PCV into the throttle body. If it's going the wrong direction (which it would have to be to have anything coming from the valve cover into the intake system), something is stopped up (typically the PCV valve isn't working).

The PCV usually sits in the middle of the valve cover on most hondas and has a tube connected to it and the throttle body. There should be a little ball bearing inside the tube that moves freely when you shake it. Check this out.

Also, the tube that goes from the PCV to the throttle body is where you'll hook the oil catch can too. It's supposed to catch any oil that might make it's way with the gases from the engine so the oil doesn't get into your throttle body.

To the guy that had the cam seal pushed out...check your PCV valve too. The pressure is supposed to be relieved through the PCV so no seal should get that much pressure when the system is working right.

I don't recommend ANYONE disconnecting the valve cover breather tube. It's part of Honda's design and has a purpose. I won't go into details other than it's functionality is basically to draw gases out of the engine. I hear it can play havoc with your crank bearings or something on the bottom end. Again, Honda put it there for a reason!

 

yes my pcv valve works properly it was the first thing i checked and replaced when i noticed this. today though i went ahead and went out and bought the stuff to make my own small catch can. and ive got it mounted. if anyone would be so kind as to help me learn to post pics ive already got the pics on my computer

and i can type up a list of the stuff i used it only cost me about 15 bucks and its nie looking and very reuseable

 

figured it out i think -- havent hooked up the hoses yet though









if you guys need it ill type up a list of parts and directions to make this

if you think its dumb then dont hurt my feelings lol i was proud of my ingenuity lol!

Pics no workie.Get copy the link from the storage bim of imagestation. Not from the album.

Edit: saw the pics, don't really fallow what you're doing. Looks like you're doing something though.
